Managing Water Resources.

Better irrigation techniques,including drip irrigation system developed by Israel has to be adopted.
Major area of concern is the high rise apartments in urban areas where they use water in enormous quantity( where there was one house previously has, now more than 48 to 50 house holds).They drill even 200 feet in metros to get water, as water table has gone down.This has to be checked.
Granting permission for multinational soft drinks companies has also contributed for water level being depleted.To augment ground water resources, rain water harvesting has to be encouraged,tanks in every village must be destilted and cleaned,delta regions of rivers must be deepened,sand quarrying from riverbeds must be checked.
Check dams need to be built to preserve water from rivers, as the water goes awaste into the sea.
For drinking water in metros where ever feasible ocean water must be made potable by reverse osmosis process.
